What is hybrid immunity for covid and what are its benefits

Hybrid immunity has been revealed as the most effective state when it comes to preventing a new SARS-CoV-2 infection. Basically It consists of a complete vaccination schedule and infection, either before or after the inoculations. The combination of the contribution of the vaccine and the body's own immune response, which also generates replica memory for future attacks, makes the person much more resistant to future infections.

The arrival of the omicron variant At the end of last November it disrupted all schemes, due to its high transmission capacity; Although it was revealed to be less aggressive than its predecessor, the delta, it multiplied infections. Its silent variant, which has been talked about in the last month and a half, has also led to redoubled caution against infections. in the midst of a climate of general relaxation, which already contemplates even the imminent end of the use of masks in indoor spaces.

The antibody response in people who have been infected with covid and have been vaccinated with Pfizer or Moderna

There were already previous studies on the matter. In the fall of 2020, a team of virologists at Rockefeller University in New York began a year-long project to try to prevent future dangerous evolutions of the virus that causes Covid-19. The goal was to create an artificial version of the Covid-19 spike protein; Various combinations of mutations on the surface of the spike protein were tested until 20 were found that seemed to make it very resistant. When the test was carried out on the blood of people who had recovered from covid-19 in 2020 and then they were also vaccinated many months later, their antibodies were able to bind to the virus and completely neutralize it. Apparently, this team found that when people who have had Covid-19 are vaccinated with an mRNA vaccine - Pfizer or Moderna - they produce an antibody response three times greater than those who received the vaccine without prior infection.
